Disc Structure
DVDs are generally divided into titles
and chapters. Usually, one movie cor-
responds to one title.
CDs are divided into tracks. Usually,
one track corresponds to one song.
Be aware when using the Player
that not all discs are organized in
this way.
Important Notes on Discs
• Never use irregularly
shaped discs with the
Player. This could dam-
age the Player and void
the warranty.
• Always handle discs by
their edges.
• Do not touch or scratch
the recorded surface or
let it get dirty.
• Do not try to play dam-
aged (cracked or
warped) discs.
• Do not use discs that
have loose labels,
exposed glue or foreign
objects stuck to them.
Composite Video (CVBS) - The recording
and transmission of video which mixes the color
information and synchronization signals togeth-
er. NTSC, PAL and SECAM are the primary
composite video color TV standards used
worldwide.
DAC (Digital to Analog Converter) – A
device that converts digital pulses into analog
signals. For example, a DVD player will have a
video DAC and an audio DAC that converts the
digital video and audio data stored on a DVD
into analog video and audio signals that can be
seen and heard via the screen and speakers
respectively.
Dolby Digital - See AC-3.
Dolby Pro Logic - A surround system where
a 4-channel audio is recorded as 2 channel and
is then restored to 4 channels for playback.
DSP (Digital Signal Processor) - A
special-purpose processor used for process-
ing digital signals for various applications.
DTS- (Digital Theatre Sound) - A digital
audio encoding technology developed by Lucas
Labs for movie theaters, and subsequently for
home theater. Like AC-3, DTS provides 5.1
channel audio, but uses less compression.
DVD (Digital Versatile Disc) - A type of
optical disc that uses very similar technology as
CDs but has a much greater capacity due to
higher
recording density. Whereas CDs
are recorded on only one side, DVDs
can be recorded on both sides and can
contain two recording layers per side for
even greater storage capacity.
DVD-Audio - With the highest possible
sound quality currently available for digital
recordings and the ability to store video and
still images as well as music, DVD-Audio is
touted by some as the next generation in
music discs. Compared to CDs that provide
44.1 KHz/16-bit resolution, DVD-Audio pro-
vides up to 192 KHz/24-bit resolution for
higher fidelity sound. Also, where CDs offer
two-channel audio (stereo), DVD-Audio offers
